BI-OGK. CIR-TILE FOR WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed July 31, 1918, Serial No. 247,566.

To all whom it may concern:

Be it known that I, HAnnY D. APPLEBY, a citizen of the United States, residing at cit and State of New York, have invented certain new and useful Improvements in Blocks or Tiles for Wall Construction, of which the following is a specification.

My invention relates to channeled building blocksor tiles employed in the construction of walls, and has for its object to provide an improved construction of block or tile embodying a positive grip for handling and layi-n the same, and also to provide for resisting lateral displacement of the blolclks or tiles when placed in position in a wa Theseobjects I accomplish in the manner and by the means hereinafter more definitely set forth and claimed, reference being had to the accompanying drawing in which Figure 1 is a perspsective view of a building block or tile, embodying my invention.

ig. 2 is a similar view taken through a portion of a wall, illustrating the manner pr cvivhich the blocks ortiles are assembled or Similar numerals of reference denote corresponding parts in the two views.

In the said drawing, the reference numerals 1 and 2 denote longitudinal load-sustaining members, the side load-sustaining members 1 being longitudinally apertured at 3, forming chambers preferably rectangular in cross area, and extending from end to end of the block or tile. The central loadsustaining member 2 has its sides 1 inclined or undercut, for the purpose of providing a ositive grip in handling the block or tile.

he load-sustaining members 1 and 2 are separated by grooves or channels 5 extending from end to end of the block or tile, and the up or or mortar-receiving surfaces of the mem ers 1 are in the same plane and constitute the upper face of said block or tile. The top surface of the central loadsustaining member 2 lies below the plane of the top surface of the load-sustaining members 1, which provides the space necessary to receive a layer of mortar or cement between the blocks or tiles at this point. The lower portions of the load-sustainingmembore 1 and 2 are connected by a transverse web 6, of substantially uniform thickness, lying below a plane passing horizontally of New York borough of Manhattan,

through the center of the block or tile, said web 6 pro ecting below the plane of the bottom surfaces of the side load-sustaining members 1. It will be observed that the top face of the central member 2 does not project above the top surfaces of the side members 1, thus avolding any protuberance above the upper face of said block or tile. Furthermore,'by forming the central longitudinal member 2 with undercut sides 4, I insure a posltive grip. Thesize and weight of these blocks necessitates that the workman shall be able to grip firmly the block or tile with has fingers in lifting and manipulating the same, as otherwise the lifting and setting of these blocks or tiles in the course of the usual days work, during which time several hundred blocks or tiles must be handled, would im ose too great a strain upon the hand of t e workman.

By providing that the horizontal web 6 shall project below the bottom surfaces of the side load-sustaining members 1, and that the top surface of the central load-sustaining member 2 shall be depressed below the top surfaces of the side load-sustaining members 1, the lateral displacement of the blocks or tiles with respect to each other more effectively is resisted, because this formation will act as a lock. This rojection 6 will not be objectionable in stacking the blocks or tiles for transportation or storage, because the depression of member 2, is substantially equal to the projection of the web 6, and the bottom surface of the latter is broad enough to give suflicient bearing when these blocks or tiles are piled in alternate layers at right an les to each other.

aving thus described my invention, What I claim as new and desire to secure by Letters Patent, is 2-- A block or tile for wall construction, comprising a plurality of longitudinal spaced apart load-sustaining members, the upper and lower surfacesof the side load-sustaining members, respectively, lying in common planes, the upper surface of the central load-sustaining member being depressed below the plane of the upper surfaces of the side load-sustaining members, and a horizontal transverse web connecting the loadsustaining members arranged substantially below a plane passing horizontally through the center of the block or tile, said transverse web projecting below the plane of the lower surfaces of the side load-sustaining members and forming with the lower portions of the load-sustaining members a base for the block, said central load-sustaining member being disposed between and spaced from said side load-sustaining members and adapted for the purposes of a hand hold, all

parts of the block being included between the plane of the upper surfaces of said side loadsustaining members and the bottom surface 10 of said transverse web. v

In testimony whereof, I have hereunto set my hand.

HARRY D. APPLEBY.
